The Keystoker 90/105 is a coal fired stove that uses patented Keystoker technology to deliver lots of heat efficiently, and cleanly thanks to the clean-burning anthracite coal used to power this stove (in rice or buckwheat sizes).

Available in a single wall 90,000 BTU version or a double wall 105,000 BTU version, this coal heater uses a patented built in heat exchanger and flat grate stoker design to produce the highest efficiency in a coal-fueled fire (up to 90%). Since this clean coal stove is fully automatic, there is no need to shake grates or shovel ashes, which saves you time. To save you even more time, and to not burden you with extra hassle, the unit comes already assembled (except for the hopper). For greater flexibility in installation, this automatic coal stove is available for chimney or direct vent system, and you can pick from two different vent locations: top or bottom.

With the heat and efficiency of a forced air furnace combined with the ambiance of a fireplace, this coal fired automatic stove proves to be a functional, efficient, and elegant addition to any home. And with an availability of 14 different colors, you can choose the perfect Keystoker stove for your home today,
